{{Short description|Hierarchy of classes of formal grammars}} [[Image:Chomsky-hierarchy.svg|thumb|right|200px|alt=The Chomsky hierarchy|Set inclusions described by the Chomsky hierarchy]] The '''Chomsky hierarchy''' in the fields of [[formal language|formal language theory]], [[computer science]], and [[linguistics]], is a [[Hierarchy#Containment hierarchy|containment hierarchy]] of classes of [[formal grammar]]s. A formal grammar describes how to form strings from a formal language's [[alphabet (formal languages)|alphabet]] that are valid according to the language's syntax. The linguist [[Noam Chomsky]] theorized that four different classes of formal grammars existed that could generate increasingly complex languages. Each class can also completely generate the language of all inferior classes (set inclusive).
